' 11 Claims.

This invention relates to stubbingdeviceaand ;more particularlytodevices for securingitogether twoadjacent poles,.or.securing the baseof one pole :to .a stub pole, as is .sometimes. necessary.

After the :poles .of telephone :lines .or electric light lines, .or the like, have zbeen .inithe ground for a period of time, they aresubject to/decay at or below the ground lineand Ebecomequite -.weak .at this :point. .Jt .is .either necessary ito .re-

move thepole and-install aznew one oriin some way provide means for .making .the base of ithe ;pole,secure. If :the pole .is=removed.and;a. new one installed,cit means, of course, .thatthe wires, .crossarms, etc.,.must all .be removedtfrom theold pole and placed .on the .new one so .that aside from the necessary .new equipment, a .considerable amount of labor .is involved.

. It .has ibeenifound satisfactory in .many :in- :stances zto avoid :replacing the pole with :a :new -.one.by inserting astub ipole orshort .polefinto athe ground adjacent .the old .one which ihas :be- :come decayed, leaving :several feet -of the :stub pole @projecting above the .ground .line. The .old :pole is ithenzsecured to .the :projecting :portion -.of .Lthe .stub .pole :by passing straps .or hands .around both and securing them as tightly together ;as .possible. Itis,.of tcourse,.desirab1e-that the: means .afor securing the apoles :together he :so arranged 'sthat -.the .old .pole will .be secured brigidly .and .:firmly atozthe stub, anditoithis'end itiis advanrtageous to provide means :fondrawing the straps .or :bandstightly about :the poles 1 after they :have :been xmounted thereon.

It :is .also desirable :to -.so connect :the parts :of the securing means that therewill beino.-relative slippage orv movement Lbetween'esuch parts and .no tendency :of .one part to :roll .or :slide 1011 the .other.

jOne object .of my zinventionxis :the provision .of anew. andimproved stubbingdeviceior meanszior securing adjacent poles itogether, such that the device may be readily 1 and (easily secured in :place and serve to bind the two .poles :rigidly and :se-

curely :together.

Another object of the invention is :the .provision of a stubloing or mole-securing device having .provision whereby Lthe straps A orlbands which embrace the pole may :be tightened :or= drawn together by bolts passing between the .poles, the bolt-securing -devicesbeing so :arranged that there will be no=possibility of movement between them and =the pole-embracing straps.

A still further object of the invention'is the provision of -a pole-securing or stubbing device which will =be positive and emcient in operation .jject over the pole .110.

and atsthesame time may be'economically manufactured and readily installed :in ;place.

To these and other 'ends {the invention consists in the novel features .and combinations -0f :parts (to be hereinafter :described and -.claimed.

. To illustrate.preierredembodimentshf .my invention, I have shown in Fig. ,1 a. pole in which ,hasbeen. cutoff-at -l l adjacent the ground line, l2 and secured to .a stub .pole -I3 installed closely .adjacentthepole .IU andprojecting several feet above .the ground in .a position substantially parallel toithe pole ,lll.

=.It willqbe noted .that two pole-securing or .30

.stubbing .devicesare. shown to secure-the poles l 0 .and .13 together, one adjacent the ground line .and .the other adjacent .the .upper end of .the stub pole. It will, .of .course, .be .understoodthat as manyof .these devicesas :is desired. eras-is .necessary .to secure .a .firm connection .may be used. .'As .the .two.devices shownin Fig. l are identical, .adetailed description of onewvill suffice forboth.

.A .U shaped strap .M is passedaroundone pole ..in .an .embracing relation, the .ends J5 10f this .strap being sufficiently long to .projectover the .adjacentpole. Inlike manner, asimilar strap 16 embraces thepole l3, .the .endsof which pro- In .the .form shown in Fig. .1, these straps will be slightly spaced vertically onthepoles and willfhave their ends-passed through and secured in castings or brackets "I61 positionedopposite each other at the front and rear 'of "the poles.

This casting I1 is shown more particularlyin '-Figs."4,-6-and7. It comprisesa plate li-ke-structure, shown in Fig. 6, having upper and lower wedge-shaped lugs l8 and 4 9 projecting :rearwardly from the face -and=designedtosenter the space between the poles. 'Rearwardly -of the and the bands drawn closely about and tightened upon the poles.

A slot or opening of keyhole shape. .25 is,

formed in the front face of the casting, and

this slot not only communicates with the open ing 22 but also communicates at its upper and lower ends with the slots Zll'and 2|, as shown more particularly in Figs. 4 and 6.-'{The-central portion of the opening 25 is somewhat enlarged,"

as shown at 26, to permit passage of the bolt '23. A washer 27, shown more particularly in Fig. 8, is provided upon each end of the bolt' 23. This washer has a substantially fiat head provided with a central opening 28 for the passage of the bolt. It is also provided with a pair of rearwardly projecting lugs 29 and 30 which, when the washer is installed, lie above and below the bolt, respectively, and pass through the upper and lower ends of the keyhole slot 25. These'lugs' are tapered inwardly, as shown in Figs. 4 and 8, and are provided on their outside surfaces with relatively sharp outwardly projecting ribs 3! and 32.

When this washer is placed upon the bolt 23, the latter is received between these l'ugs,-an-d the head of the washer may be struck with a hammer to drive it in place. The ends of the lugs 29 and 30 pass into the opening 22 of the casting I1, and the ribs 3| and 32 will be caused to bite into the lower and upper edges of the straps I6 and M, respectively. This hammering of the washer may be done before the bolt 23 is inserted therethrough. The ribs on the washer lugs will, by biting into the straps, interlockwith the straps and hence prevent any slipping of the latter through the slots of the casting II. In other words, the straps will thereby be locked to the casting, and when the nuts 2 are tightened upon the bolt 23, the straps will be caused to bind about and closely embrace the respective poles.

Also, as the bolt 23 is locked within the castings I1, and as these castings are secured to the straps, there will be no tendency when the nuts are taken up upon the bolt 23 for the latter to twist or move, but on the other hand the entire assembly will be held rigidly in position.

It will be understood that the lugs I8 and I9 will fit in between the two poles and resist any tendency that the casting might have to roll or move about the surface of the poles; As the nuts are tightened and the straps drawn inwardly from the position shown in Fig. 2 to that shown in Fig. 3, thetension of the straps I 6 and I I will tend to act as a couple pulling the upper endof the casting II in one direction and the lower end in the other direction. This will be resistedby ends of the straps, through which lags may be driven into the poles to secure the ends of the straps tightly thereagainst.

In Fig. 9 I have shown a slightly modified form .Figs. 1 to 8.

them together.

of my invention. In this form the castings I 1a are substantially like the casting I'l heretofore described, except that the slots for the passage of the straps will be slightly deeper so as to permit the ends of two straps to be passed through each of the slots in superposed position instead of one strap, as shown in Figs. 1 to 8. In this instance a U-shaped strap 35 will be passed about one pole, and a U-shaped strap 36 will be passed about the other pole at the same level, the ends of these straps overlapping each other and passing through the same slot in the casting Il'a in superposed position. A similar pair of straps will be mounted below those just described to be passed through the other slot of the'casting Ila. In other words, in this form of my invention four straps will be employed in each connection instead of two, as shown in Fig. 1. In other respects this form of my invention is like that described in connection with While I have shown and described a preferred stoodthat it is nottobe limited to all of the details shown, but is capable of modification and variation within the spirit of the invention and within the scope ofthe appended claims.
